Abstract
Provided are a compressor and a monitoring system that can specify a cause of an anomaly of a sensed value of a sensor. A compressor () includes: a temperature sensor (A) that senses a temperature of a compressed air on a discharge side of a low-pressure-stage compressor body () and on an upstream side of an intercooler (); a pressure sensor (A) that senses a pressure of the compressed air on the discharge side of the low-pressure-stage compressor body (); a temperature sensor (B) that senses a temperature of the compressed air on an intake side of a high-pressure-stage compressor body () and on a downstream side of the intercooler (); a temperature sensor (C) that senses a temperature of the compressed air on a discharge side of the high-pressure-stage compressor body (); a controller () that decides whether or not an anomaly has occurred in sensed values of the sensors (A), (B), (C), and (A), and estimates a cause of the anomaly; and a display device () that displays the cause of the anomaly estimated by the controller ().
